Abstract: Based on Arrhenius Power law model, the numerical methods for analysed grouping the data of Constant Stress Accelerated Reliability Growth Testing(CSARGT) were given.They included the statistical tests of four fundamental hypotheses of CSARGT, the Maximum Likelihood Estimation(MLE) and interval estimation of the parameters of the power law model and MTBF at accelerated stress levels S i ,the Best Linear Unbiased Estimation(BLUE) of the coefficient of acceleration equation, the interval estimations of acceleration factor and converted MTBF at normal stress level S o. These methods were illustrated.
